Visualising Key Chess Squares by Piece

Using the Kasparov-Karpov data-set, this visualisation shows relative occupation times for each square. The occupation times can be filtered by type of piece (knight, bishop etc.). Comparing games with Kasparov playing white with those of Karpov shows a clear difference, reflecting the different playing styles and strategies of the two.

Using Parallel Sets to Visualize Chess Openings

An attempt to capture the multi-dimensional complexity of chess openings, using the data-set of all games played between Kasparov and Karpov.

Visualising Chess Openings with Packed Circles

The use of packed circles to visualize the opening variations of the 135 games played between Kasparov and Karpov. D3's packing library does the placement leg-work. Part of an on-going series.

54 Chess Games: Kasparov vs Karpov

Sometimes it's good to imagine something a little exotic and then try and realize it using the tools to hand. So here we have a simultaneous chess tournament featuring 54 random games from the great Kasparov vs Karpov series of the 80s and 90s. Using D3, THREE.js, CSS3D and a few helpers they are superimposed on a giant rotating cube because, why not?

Colorbars: Building a D3 Plugin

Some thoughts on best-practice for building a D3-plugin, using a colorbar example. The aim is to limit boilerplate code, increasing resusability and a general ease-of-use. Very much a work-in-progress.

D3 Gothic Window Generator

A rainy bank-holiday Monday was a good excuse to try and indulge my aesthetic whims. Something to overload the frontal cortex with colors and symmetries, something a little like a Gothic Rose Window in fact. Once one begins to get D3, rolling this kind of stuff together gets a lot easier and faster. I liked the effect so much I added the ability to change number of segments and number of triangular elements in each.

D3+Angular+Bootstrap Active-data Console

A recent client wanted a way to filter a large dataset of objects while seeing any changes immediately reflected by data-selective charts. Using Angular directives for two-way data-binding and Bootstrap for placement and dimensions, a few lines of XHTML is all it takes to build a console.

D3 Chess Viewer

I needed a chess-viewer for a larger data-viz project I'm working on and D3 seemed like the perfect tool for the job. The viewer takes lists of moves (SAN format) and creates an animated play. It could be a nice base for something more full-featured. Once again I was impressed by how easy D3 makes this kind of project.

Warped England: Why Young People Can't Buy Houses Anymore

A D3 maps visualization of the change in the ratio of English house-prices to household incomes over the period 1997-2012. By warping the map of England to reflect the increase in this ratio and reciprocal decrease in households' house-buying power, we see the dramatic economic disempowerment of current and future English generations.

Tech4Good Awards Glowstick Voting

The estimable Paul Hayes and myself raced against the clock to provide a glossy new take on the art of glowstick voting. Using a decent webcam, Python's computer vision fu (SimpleCV channeling OpenCV), the wonders of web-socketry, courtesy of Flask and SocketIO, and some rather gorgeous Javascripted GPU-shader wizardy we were able to turn a bunch of vertical glowsticks into a vote (Huzzah!).

Visualizing Smartphone Accelerometers with D3

The phone in your pocket isn't just recording your position by satellite and wifi signal (and sending it on to who knows where?), it also has little accelerometers which monitor the way the phone moves. This visualization takes data from an academic study, showing that phone users can be distinguished by their unique walking 'signature'.

Getting Your Python Data onto a Browser

A short, practical guide to making the leap from OS-based visualizations to something you can share with the world at the click of a button. Starring Python, Javascript and D3.

D3 Bespoke Histogram

A bespoke D3 histogram, with synchronizing axes. The variable radius and color of the plotted circles allows the representation of four dimensions, the x and y axes and two other counts.

D3 Generated Menu

A recent job required a menu that lets one progressively filter a packet of row-column data, drilling down to items of interest. It was refreshing to use D3 outside of charting and it dealt with the necessary DOM manipulations with ease.

Historical UK Weather

I used Python and D3, the Javascript visualization behemoth, to transform some old pages of row-columnar data provided by the UK Meteorological into an animated coloured map, showing hours of monthly sunshine, millimetres of rain and maximum temperature.

Python, Javascript and Web-visualizations

A recent talk I gave at Pydata London 2014, which covered the various ways in which Python's data-analytical skills can compliment Javascript's burgeoning power web-side.

Braitenburg's Vehicles

One of the very few great books to come out of Cybernetics, Cognitive Behavioural Studies, Neuroethology etc., is Valentino Braitenberg's Vehicles. Probably the best known vehicle is the light-loving photovore and the demo shown scratches a personal itch - what happens when a group of photovores, each carrying a light source, are let loose. Play around with the parameters on the left to alter the characteristics of the ensuing mayhem.

Swarming boid's

Craig Reynold's original Boids demonstrated how natural looking animal flocking and swarming could be produced by applying very simple rules to each 'animat', governing things like distance to neighbours, centre of mass of neighbouring animats, avoidence and convergence tendencies. This demo lets you play with the parameters while the boids fly around - changing the quality of the swarming.

Great LIBOR bank robbery

At a recent Brighton Digital Hackathon the topic was the Financial Crash 2007. I produced this animated D3 chart to show the extent to which LIBOR, the inter-bank lending rate, was manipulated by bankers, a multi-billion dollar fraud.

WebGL fireworks

I built a little programmatic fireworks display for a talk I gave on THREE.js, my favourite WebGL Javascript library. Such mini-projects are a great way to pick up skills - getting the THREE.js skymap down proved a little tricky (hint: you need two cameras).
